Ultra-High Barrier PET Aluminum-Coated Film
Product Introduction:
This film features a specialized base layer with water-based coating solutions to enhance water barrier performance. The external aluminum coating further improves oxygen barrier properties, achieving dual barrier performance below 0.5. It offers exceptional moisture and oxygen barrier performance to extend shelf life and provides excellent light shielding, protecting packaged contents from UV damage.
Product Applications:
Widely used in the packaging of tea, coffee, chocolate, spices, and pharmaceuticals. Also suitable for applications in electronics, labels, cosmetics, and metal products.
